Title: Fuel injection pumping  apparatus
IPC: F02D41/38
Filed: 1973-06-01
Abstract: 1460430 Automatic control of IC engine fuel injection pumps BRYCE BERGER Ltd 28 May 1974 [1 June 1973] 26298/73 Heading G3R Each fuel injector of the plurality needed on a multi-cylinder I.C. engine is connected in its own feedback control loop and is supplied with a common signal representing the required quantity of fuel. The quantity of fuel injected is controlled and represented by the position of rod 12 which is signalled by transducer 17 and compared in amplifier 15 with the fuel demand signal from circuit 18 to produce a signal which causes drive circuit 14 to operate actuator 13 to change the position of rod 12. The fuel demand signal from circuit 18 is derived from a comparison in amplifier 20 of the operator throttle demand 21 and actual engine speed from A.C. transducer 22 via converter 23. The circuit 18 acts as a discriminator and also receives a maximum fuel signal from circuit 19. The arrangement may also be provided with a safety circuit for removing the power from the actuators in the event of a fault.

Title: Improvements in or relating to electrical conductors
IPC: H01B7/29
Filed: 1949-10-14
Abstract: Aluminium or aluminium-coated conductors are insulated with polymeric chlorotrifluoroethylene by passing the conductors through a dispersion of the polymeric material and then heating to volatilize the liquid phase of the dispersion and to fuse the polymeric material to a smooth sheath.  The polymeric material is powdered in a hammer mill and then mixed with a dispersing liquid such as high-flash naphtha, butyl alcohol, benzene, toluene, xylene or ethylene glycol, and mixed in a pebble mill to obtain a homogeneous dispersion which may be maintained by agitation.  For example, 15 parts of the polymeric powder may be mixed with 85 parts of a liquid dispersing medium comprising 2/3 by weight of high-flash naphtha and 1/3 n-butyl alcohol.  The mixture is milled in a pebble mill for 168 hours.  A conductor coated with this dispersion is passed through an oven whose temperature varies from about 150 DEG  C. at the entrance to about 500 DEG  C. at the exit.  The dispersing medium is volatized at the lower temperature and the polychlorotrifluoroethylene coalesces at the higher temperature.

Title: Improvements in components of clockwork and like mechanisms and processes for their manufacture
IPC: G04B31/08
Filed: 1958-08-18
Abstract: A permanently lubricated component of a clockwork mechanism comprises a tightly adhering non-sticky coating on at least the parts subjected to friction, the coating containing an inorganic salt dry lubricant mixed with a synthetic polymer material and having a thickness of up to 1 micron.  The inorganic dry salt lubricants which may be used are inorganic salts (other than molybdenum disulphide) which are lubricants and are insoluble or only very difficultly soluble in water, e.g. lead iodide, mercury iodide, silver iodide and silver sulphate.  The synthetic polymer may be as described in Specification 864,531.  Plasticizers, graphite, molybdenum disulphide and cellulose derivatives may be included in the coating materials, which may be applied as aqueous or non-aqueous suspensions, e.g. by dipping. After drying, the coatings may be baked or sintered, preferably under high pressure in an autoclave.  In an example, cleaned clock main springs are immersed in a bath of an aqueous dispersion of lead iodide and polytetrafluoroaethylene, the bath being subjected to ultrasonic vibration.  After 30 minutes the springs are withdrawn, excess suspension is removed, and they are dried at slightly elevated temperature.

Title: Gear honing machine
IPC: B23F19/05
Filed: 1960-07-29
Abstract: 911,217. Gear - finishing. NATIONAL BROACH & MACHINE CO. July 29, 1960 [Sept. 14, 1959], No. 26551/60. Class 83 (3). A modification of the gear honing machine claimed in Specification 882,597 comprises a light tool support 54, Fig. 3, angularly adjustable in the tool head 50 about an axis perpendicular to the tool and work axes. The work is clamped by a pneumatically-operated tailstock 24 on a work-support 20 adjustable about a central pivot and supported by bearings 32. The work-support 20 carries an angularlyadjustable slotted bar engaged by a pin 34 on a slide 12 to produce crowning of a gear. The tool T is rotated by a motor 52 carried on the head 50 which is adjustable angularly by gearing 58 on a slide 44 adjustable transversely on the slide 12. The shaft 66, Fig. 5, carrying the tool T, is rotated through a universal coupling 152 in bearings 64 in the light support 54. The support is carried on a shaft 74 axially-movable in an angularly adjustable member 76. The head 50 carries a support 82, Fig. 6, for a slotted block 86 adjustable angularly by gearing 94 against a dial 96. The block 86 can be urged downwardly by a solenoid acting against springs 101. to move it into contact with a follower 116 mounted on the shaft 74. Thus, when the head 54 is moved axially of the shaft 74, by means such as is described in Specification 911,216 to mesh the tool with the work, the block 86 causes angular adjustment of the head. This angular adjustment compensates for wear of the helical teeth of the tool. To lock the head 54 angularly, an air cylinder is actuated to operate toggle linkage 138 and clamp brake arms 120 against a drum 80 on the member 76. When the head is locked, the block 86 is retracted.

Title: Improvements in or relating to charge-discharge arrangements for a gas-cooled heterogeneous nuclear reactor
Inventor: AYRE JAMES LEWIS
IPC: G21C19/08
Filed: 1959-08-04
Abstract: 908,130. Servicing reactors. SIMONCARVES Ltd., and GENERAL ELECTRIC CO. Ltd. July 29, 1960 [Aug. 4, 1959], No. 26564/59. Class 39 (4). In a gas-cooled reactor of the type having fuel elements in channels in the moderator core it is arranged that the drop in gas pressure along a selected channel may be increased for the purpose of charging and discharging fuel elements into or from that channel. The channels may be horizontal or vertical and the pressure drop may be increased by a blower. As shown, a selected channel 2 is coupled to the extendible charge tube 7 of a travelling charge/ discharge vessel 5 and the pressure drop in the channel is increased by a blower 6 having a flexible connection with the pressure vessel 3. In use, an extendible chain is operated from the vessel 5 to engage the top fuel element in the channel and the blower 6 is operated to levitate the column of fuel elements, whereupon the chain is retracted and the column follows it, the column being finally secured in a magazine in the vessel 5. In a charging operation the chain pushes a fuel element column into a channel against the levitating force of the gas. To safeguard against failure of the blower during a fuel transfer operation the column of the vessel 5 may be made large enough to permit completion of the operation; alternatively, the vessel 5 may vent to a container 10 through a valve 8 and produce an adequate pressure differential across the channel. The arrangement permits pre-heating of the fuel elements about to be loaded into a channel without additional equipment. Specification 791,011 is referred to.

A ring in a compression pipe joint having two threaded clamping members 10, 15 has tapered ends 19 separated by a thicker, plain cylindrical inner portion 20 and has circumferential grooves 21 between the inner portion and the tapered ends. The tapered end portions are pressed against the pipe 11 by the chamfered edges 14, 17 of the clamping members when the members are screwed together and the grooves 21 weaken the ring to allow this to happen without undue expansion of the central portion of the ring. In a preferred embodiment the tapered edges of the ring have a cone angle of 30 degrees while the cone angle of the chamfered edge of clamping member 15 is 90 degrees and that of member 10 is 60 degrees, thus producing an angle of divergence between the clamping members and the ring of 30 and 15 degrees respectively. This difference allows member 15 to provide the axial force required to move the ring along the pipe while producing equal radial compressive forces on each tapered end of the ring.
